| Abstract: | This paper briefly reviews development history of Airborne Lidar Bathymetry (ALB),introduces a few primary foreign ALB systems with its core performance parameters,then discusses chief merits and demerits of these ALB systems in detail.On the basis of ALB flying experiment,the paper systematically summarizes several key technical problems of ALB operation procedures,such as installed position of GNSS antenna on airborne,testing GNSS signal quality,selecting and surveying calibration field,selecting operation meteorological condition,designing survey line,and transforming depth datum from mainland to isolated island,and so on.Lastly,the problem of setting ALB operation specification is discussed. |
